#x= -10#

First, subtract #20# from both sides of the equation so that the right side of the equation only has one term. This will give you

#-20+x=3x#

Next, subtract #x# from both sides so that only one side has a variable. Now you should have

#-20=2x#

The last step is to divide both sides of the equation by #2#, which will give you

#-10=x#

You can double check to see if this is the solution by substituting #x# with #-10# in the original equation.
